GS4A021822CT Description

The GS4A021822CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 18.2 kΩ and an ultra-tight tolerance of ±0.25%. The network operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in harsh environments. Its ±50 ppm/°C temperature coefficient minimizes resistance drift, making it ideal for precision circuits. The SOIC package (4.9 mm × 5.99 mm × 1.45 mm) with gull-wing terminations facilitates easy surface-mount assembly, while the ceramic construction enhances thermal stability and durability.
